Abstract: 目的探讨经颅多普勒(TCD)在椎基底动脉狭窄诊断中的应用价值。方法选取经TCD检查为椎基底动脉血流异常的缺血性脑血管病患者108例,于住院一周内行数字减影血管造影(DSA)检查,比较两种方法对椎基底动脉的检测结果。结果108例患者共检测椎动脉、基底动脉320条,TCD发现狭窄椎动脉78条,基底动脉22条;DSA发现狭窄的椎动脉104条,基底动脉36条。以DSA为金标准,显示TCD诊断椎动脉狭窄的特异性、敏感性为71.8%,假阳性、假阴性率为28.2%,基底动脉狭窄的特异性、敏感性、假阳性率、假阴性率分别为90.0%、87.5%、36.4%、2.7%。结论TCD对基底动脉狭窄的诊断具有较高的特异性和敏感性,对椎动脉狭窄的诊断有一定的特异性和敏感性。
